Casio MQ-24 Battery Replacement
A Casio MQ 24 battery replacement is simple in theory, but the snap-back case can be tricky if you have never opened a watch before. The biggest risk is scratching the case, bending the case back, or damaging the gasket.
Tools you need:
| Tool | Why you need it |
|---|---|
| Small case knife or watch case opener | To lift the snap-back cover |
| Plastic tweezers | To handle the battery safely |
| SR626SW battery | Correct replacement battery |
| Soft cloth | To protect the watch crystal |
| Small tray | To keep parts from getting lost |
| Case press or careful pressure | To close the snap-back cover |
Basic steps:
- Put the watch face down on a soft cloth.
- Find the small notch on the case back.
- Use a thin case opener to carefully lift the snap-back cover.
- Note the position of the gasket before moving anything.
- Remove the old battery.
- Insert the new SR626SW battery in the same orientation.
- Check that the second hand starts moving.
- Make sure the gasket is seated correctly.
- Press the case back closed evenly.
Important: do not use a sharp kitchen knife if you can avoid it. It can slip, scratch the watch or cut your hand. A cheap watch case opener is safer.
Casio MQ-24 Battery Change: Common Mistakes
| Mistake | Why it matters |
|---|---|
| Using the wrong battery | The watch may not work or the battery may not fit correctly |

| Losing the gasket | Water resistance can be reduced |
| Touching the movement too much | Dirt or oils can affect the small parts |
| Forcing the case back | Can bend the back or damage the case |
| Closing the back unevenly | May pinch the gasket |

The most common mistake is buying a battery that looks similar but is not the correct size. For the Casio MQ-24, search for SR626SW rather than guessing from another Casio model.

Casio MQ-24 Battery Price

| Option | Approx. price in the US |
|---|---|
| Single SR626SW battery | About $2-5 |

| Watch shop battery replacement | About $10-20 |

| Casio G-Shock | Varies by exact model |
| Casio solar watches | Rechargeable solar cell |
If you are asking what battery does a Casio watch take, always check the exact model number. The MQ-24 uses SR626SW, but another Casio watch may use a completely different battery.
